-----------------------------------
Summary: Properties from configoverlay.json are not working in
dataimporter config
Key: SOLR-11529
URL: https://issues.apache.org/jira/browse/SOLR-11529
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - DataImportHandler
Affects Versions: 7.1.0
Reporter: Shawn Heisey
Properties set in the config overlay (configoverlay.json) are not working in
the dataimport config, but they DO work in solrconfig.xml.
A user in IRC reported the issue, and I duplicated it. I set up a cloud
example, then adjusted the config and jars so that it would allow setting up a
DIH handler. I did *not* add any JDBC driver jars.
One of the properties added with the config API was "solr.db.driver" with a
value of "com.mysql.jdbc.Driver". I modified the LTR transformer already in
the config to use ${solr.db.driver} for the class. That resulted in an error
message, and the error said that it couldn't load com.mysql.jdbc.Driver ... so
I knew that the property substitution had worked.
Then I tried to use the same property inside the dih-config.xml file referenced
by the DIH handler. This also failed, but didn't mention the mysql driver
class. So I modified the class to ${solr.db.driver}.foo, which resulted in the
following error:
{code}
Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException:
org.apache.solr.handler.dataimport.DataImportHandlerException: Could not load
driver: .foo Processing Document # 1
{code}
This tells me that the properties were not loaded when DIH parsed its config.
